Enable Beta APIs

Last updated: July 23, 2026

Enable the Beta APIs experiment for a NolimitHost Minecraft Bedrock Edition world through World Manager or level.dat.

Enable Beta APIs only when a Bedrock add-on requires experimental script APIs. An add-on is a pack that adds new items, mobs, or behavior to the game, and some add-ons need experimental scripting APIs to run. You can use World Manager or edit the active world's level.dat file — the world's settings file that Bedrock stores inside each world folder.

Before you begin

  • Confirm that this is a native Minecraft Bedrock Edition server — a server running the official Bedrock server software, not a Java server using Geyser cross-play.
  • Check that the add-on specifically requires the Beta APIs experiment. An experiment is a toggle in the world settings that turns on beta features.
  • Stop the server before changing the world, so the running server does not lock or overwrite the world files while you edit them.
  • Create a server backup before changing the world.
  • Identify the active world — the world the server actually loads — before using the file method.
Warning: Beta APIs can change or be removed in later Minecraft versions. After you enable an experiment for a world, you cannot return that world to a non-experimental state. Keep an untouched backup.

Using World Manager

  1. Open World Manager — Log in to the NolimitHost Game Panel at https://panel.nolimithost.cc/ and select your Minecraft Bedrock server. In the left sidebar, click World Manager.
  2. Edit the active world — Find the world currently used by the server and select Edit.
  3. Open Experiments — Go to Experiments, then enable Beta APIs. The Experiments section lists the beta toggles you can turn on for the world.
  4. Save and restart — Save the world settings, restart the server, and watch the console for add-on or scripting errors. A restart is required so the world reloads with the new experiment enabled.

Using level.dat

  1. Open the active world folder — Log in to the NolimitHost Game Panel at https://panel.nolimithost.cc/ and select your Minecraft Bedrock server. In the left sidebar, click File Manager, then open worlds/<active-world>, replacing <active-world> with the folder used by the server.
  2. Open level.dat — Select level.dat to open the world-data editor, which lets you change the world's settings directly.
  3. Enable Beta APIs — Find the Experiments section and enable Beta APIs. Save the file.
  4. Restart and verify — Restart the server and watch the console. Confirm that the add-on loads without a missing experiment or unsupported API error.
Note: Use World Manager when possible. The level.dat method is useful when you need to edit the active world directly.

If Beta APIs does not work

  • Confirm that you edited the active world — the one the server loads — rather than another folder in worlds.
  • Stop the server before saving level.dat, then restart it after the change.
  • Confirm that Beta APIs remains enabled after reopening the world settings.
  • Check the add-on's manifest.json and installation instructions for its required Minecraft and script API versions.
  • Restore the backup if the world or add-on stops loading correctly.
